Cain's Journal

Were you looking for the journals that form part of A Quick Study achievement, Deckard Cain's Journal and Cain's Old Journal?

Cain's Journal explains a lot of the events that took place in the Diablo games up until the third instalment, and excerpts of it can be found here. Some of the graphics used for Deckard Cain's handwriting is a little bit unclear, and you should look at the Sanctuary Calendar for further help. You can also find interesting findings in the timeline.

These dates are canon, as stated by Blizzard, but has been retconned between the time of WWI 2008 when they were added and 15th of January 2010, when they were discovered to have been changed. You can find the original version of Cain's Journal in the Archive.

The below is from an interactive journal that appeared on Blizzard's old Diablo 3 site.

29th day of Jerharan

Pages 0-1.

The events of the past year are unbelievable, and have driven me to write again my thoughts. No matter how hard I try, the facts are unavoidable: our King Leoric has gone mad, lashing out in crazed frenzy at the abduction of his son, Albrecht, and our steady losses in the ill-advised war against Westmarch, leading to an open revolt among our guards. There is something almost palpable in the air. It feels like...terror.

1st day of Damhar

Pages 2-3.

Can the old stories be true - can the tales of the brave Horadrim and the Lords of the Burning Hells be more than a legend, a fairytale told to me by my mother?

I used to thrive on those tales of bravery and heroism. I'd imagine myself as one of them: the mysterious Horadrim led by the inscrutable Tal Rasha! I was so proud to be the "Last of the Horadrim", the one who would travel the world fighting evil wherever it dwelt. Ah, the boundless energy of youth.

Could there be some basis in truth to all these tales? The signs all point to this but how is someone with my education, my knowledge, to take these tales seriously?

Is there really some dark entity buried beneath our own town? If only my aging mind could remember the tales as vividly as I did in my younger days.

12th day of Damhar

Pages 4-5.

I am a fool. If I had acted sooner, if I had voiced my concerns, they would not be dead; Farnham would not be the drunken sot he now is. Lazarus, supposed Archbishop of Light, has lured a group of villagers to their horrific end under the guise of searching for the king's missing son. Is he the architect of the evil that has befallen the town, or simply an unwitting pawn?

The nights are long, and as I sit and listen to the hellish drones emanating from the cathedral, I begin to see my path clearly before me. I shall return to the texts. There must be an answer, a way to defeat this evil that torments us.

20th day of Damhar

Pages 6-7.

Each new terror sends more townspeople fleeing. There are only a few of us left now: Griswold, Pepin, Ogden, Farnham, the unfortunate Wirt, and, of course, the fair Gillian. There is someone else, however: someone who has come, while others flee. I am not so sure what to make of this Adria, who openly calls herself witch. She has access to all manner of arcane knowledge that even I do not. Why has she come here now, at this heinous time? I feel there is something amiss about her.

27th day of Damhar

Pages 8 and 9.

Every dawn seems to bring more adventurers into our midst. But none who can yet be called hero. I bide my time and continue scouring the old texts for answers. If only I had taken them more seriously, not dismissed them so lightly!

1st day of Ratham

Finally one of these adventurers seem to stand out from the rest. Though a man of few words, he radiates a calm and focus that unnerve the others, who are only interested in pillaging and looting. I feel I have come to know this hero, this wanderer. I have revealed my history and shared my knowledge with him. I hope it is enough.

21st day of Ratham

Pages 10 and 11.

I have suspected for a time now the true nature of the evil that us at the heart of our troubles, but it was too horrible to admit the truth of it. But the time for denial is past: it is the Dark Lord of Terror, Diablo himself, who plagues us.

The vile staff of Lazarus was brought to me today, further confirming my suspicions. There is no longer any doubt that he is the one who kidnapped Albrecht and perhaps even freed Diablo from his ancient prison. Who knows what further treachery he has planned? Luckily I suspect Lazarus has not long to live if our champion has anything to say on it.

6th day of Esunar

Pages 12 and 13.

I dreamt of the death wail of a small child tonight. It tore up from the depths, shattering the windows of the decrepit cathedral. As I started awake, it became apparent that it was actually the shriek of Diablo's tortured end. Unable to return to sleep after such an unsettling cry, I ventured outdoor to await the warrior's return. He finally emerged, covered in blood -- much his own, much his enemies'. I am greatly relieved that he survived the ordeal, and that these horrible events are now in our past. But my mind is troubled, for could this not have been avoided I had not dismissed my legacy so lightly?

18th Day of Esunar

Pages 14 and 15.

I have never seen Tristram bursting with such joy as in the weeks since Diablo's defeat. The town's quiet, brooding hero, whom I am proud to call friend, has humbly endured these celebrations. Yet it seems clear to me that the scars he gained beneath the church run deeper than those upon his skin and may have changed him forever. I have offered counsel, but he remains distant. Time, perhaps, is the only thing that may heal him.

20th Day of Esunar

Pages 16 and 17.

How could I have been so blind? I believed my friend's melancholy to be a natural reaction to the horrors he had lived. How could I not have seen that he carried within him the very being of Diablo? After brooding for weeks, he finally slipped away in the night. Perhaps he has gone to "the east" that he so often woke screaming about in the days following his victory over the Lord of Terror.

Shortly after he left us, legions of foul demons attacked and burned our town to its foundations. None of the townspeople were spared, and not even the women or children were allowed peace of the grave. Instead, all were reanimated in grisly undeath. And Griswold, who had so faithfully armored the one I had called friend during his battles, suffered perhaps the worst fate of all, being corrupted into a slavering demonic beast thirsting for human flesh.

This is no simple madness. It can be nothing less than possession by the Lord of Terror himself. The fool, he thought he could contain Diablo's evil. His reckless overconfidence has proven costly to us all.

I sit now, caged, amongst the screams and the hellfire, as I await my own end.

2nd Day of Kathon

Pages 18 and 19.

Although I had long given up hope and surrendered to my inevitable fate, the impossible happened today. I was rescued. Heroes have come to Khanduras to combat the corruption that the man I've come to call the Dark Wanderer has brought upon these lands. He had long since departed on some unknown mission, but they could not follow until they defeated the vile demoness Andariel, who barred the only passage east. I have decided to join them, in the hopes that my knowledge of the ancient ways might be of some help.

15th Day of Solmoneth

Pages 20 and 21.

Our sense of relief is overwhelming now that our passage through the desert is finally over and we have arrived in Lut Gholein. Though I tell no one, Diablo's terror has left its mark upon me as well. I wake in the night, suffering unholy visions of the destruction visited upon my home, the slaughter of the helpless villagers, and the echoes of dark acts perpetrated beneath the earth. I hope that these will pass in time, but I fear that I will never escape them.

I spoke with the people of the town for a clue to the whereabouts of my former friend, but information is scarce. We have learned that he does not travel alone: he has a companion named Marius. I can only wonder what part he plays in all of this.

11th Day Lycanum

Pages 22 and 23.

We are too late. My companions followed the trail of the Dark Wanderer to the tomb of Tal Rasha, only to be confronted by the demon Duriel. Baal's Soulstone was nowhere to be found. We can assume that Baal is free once again, and that he and the Wanderer have departed for Travincal to free their brother, Mephisto. This must not be allowed to happen.

1st Day of Ratham

Pages 24 and 25.

Today I have seen what has become of the man who once risked everything to save us from the Lord of Terror. It was here in the jungles outside Kurast that we caught our first fleeting glimpse of the Dark Wanderer. It saddens me to think that even as steadfast and noble a hero as he has proven insignificant beneath the corrupting influence of the Lord of Terror. I weep for what he once was, and yet I curse him for the arrogance that has led him to his path, sowing pain and death across our world.

Mephisto's resurrection in our world was brief; my companions have seen to that. They fought through horrors I can scarcely imagine to defeat him and reclaim his Soulstone. They also brought back the devastating news that the Wanderer was no more. All traces of his humanity had been eradicated; he had been completely overtaken by Diablo in mind, body, and spirit. Fortunately they have succeeded in driving him back to his fiery home, and they tell me they mean to assault the Burning Hells in order to put an end to this existence once and for all. I can only wish them luck.

1265 Anno Khejistani

4th Day of Kathon

Pages 26 and 27.

Diablo is dead. I have long desired to hear these words, but now that they come, I feel little joy. News has also reached us of a demonic army marching upon Arreat. This is Baal's doing, no doubt. We depart for the north with the tide. Still, we must count our blessings: the Soulstones of Mephisto and Diablo have been destroyed at the Hellforge and they will trouble us no further. Only one remains.

2nd Day of Vasan

Pages 28 and 29.

The cold of the northern mountains chills me to my old and weary bones. Baal's army holds the mountains passes from our haven in Harrogath all the way to the summit. The honor, strength and dedication of my companions never cease to amaze me. They are even now braving the demons and snow to reach Baal himself. Rumours of betrayal swirl through the town. This time, we must not be too late.

10th Day of Vasan

Pages 30 and 31.

It seems we are cursed. Even in victory, we face defeat. Although the heroes destroyed Baal, the angel Tyrael has delivered grave news. An object of great power that he calls the Worldstone was held in secret at the mountain's summit, and it had been corrupted by Baal. He believes the only option open to him is to destroy it. I know too little of this Worldstone and what powers it may hold to guess what might come of this, but I fear our actions may scar the world in ways we cannot know. I pray Tyrael is making the right choice.

Pages 32 and 33.
